“I’m very happy to win my first ever WTA singles title, especially with my low back injury and the hot weather here,” said Duan who was saved mid-match by the WTA on-court coaching rule, where male coaches swoop on court to rescue women players by imparting tactical advice. “Vania played really well in the first set. My coach gave me some advice during the second set. He asked me to improve my speed a bit and I did so. It worked.”
